I ordered a new left transmission cooler hard line from the dealer.
We looked up the P/N on his parts system and came up with 123 270 46 96.
My old line was damaged at the fitting for the flexible line.

The line is approximately the right length, and has bends in the right places,
but the diameter of the banjo fitting is too small! The bolt won't
pass thru the line. We looked again at the parts system, and it shows only
123 270 46 96 as valid.

Car is an '82 300D. Anyone have any idea what's happening, and
what the right p/n might be?
